QueryModel IN should allow integer/long parameters

I have a NXQL query which contains a WHERE someid in ?, and then I use the QueryModel.getDocuments to execute the query.
The datatype of someid in the database is not String/VARCHAR, but an INTEGER/LONG.

I am not able to execute this query, since the NXQL is not expanded into proper JDBC.

Long[] ids;
Object[] params = new Object[] { section, ids};
DocumentModelList res = qm.getDocuments(session, params);
